Introduction

Enrichley helps you build and clean B2B prospect lists — and lets you do it from wherever you work: the app, the API, or your AI assistant.
  • Email validation — high-quality validation with a special emphasis on catch-all and other “risky” addresses. Instead of throwing those away, Enrichley helps you safely recover more of your list and protect your sender reputation.
  • Lead discovery — build targeted prospect lists with People Search, find companies similar to your best customers with Company Lookalike, and resolve work emails for saved people with Email Finder. Export the results to CSV, Clay, or HubSpot.
  • Agent access — connect Claude, Cursor, or any MCP-compatible assistant to your account with the Enrichley MCP server, and run all of the above in plain language at the same prices.

​
Key features

​
Email validation for real-world lists

  • Validate individual email addresses through the API.
  • Detect and handle catch-all domains so you don’t need to discard them by default.
  • Designed to keep bounce rates low while maximizing the number of usable contacts.

​
Lead discovery

  • People Search — build a list of people by role, seniority, location, company profile, and more.
  • Company Lookalike — turn a few seed domains into a list of similar companies.
  • Email Finder — find work emails for your saved people, billed only when an email is found.
  • Export results to CSV, Clay, or HubSpot.

​
Your AI assistant, connected

  • The Enrichley MCP server brings the whole product into Claude, Claude Code, Cursor, VS Code, Codex, and other MCP clients.
  • Free previews and quotes; every paid run needs your explicit confirmation.
  • Same account, same credits, same prices as the app.

Benefits

​
Recover more valid emails

On many unverified lists, 40–60% of emails are considered “risky” because they’re on catch-all domains. Enrichley is designed to safely recover a large portion of those addresses, often resulting in 20–30% more valid emails on the same list compared to traditional verification tools.

​
Protect sender reputation

By validating emails before you send, you reduce hard bounces and help keep your sending domains and IPs healthy. Enrichley’s real-time checks are tuned to help keep bounce rates low when used with clean data sources.

​
Use your data more efficiently

Data is expensive. Rather than discarding a large percentage of your list due to catch-all results, Enrichley lets you keep more of the prospects you’ve already paid to acquire.

​
Use cases

  • Sales & marketing teams – Build prospect lists, find and validate emails, and preserve valuable catch-all leads instead of deleting them.
  • Email deliverability & ops – Monitor list quality across different sources and maintain strong sender reputation.
  • Product & engineering teams – Integrate validation checks directly into signup flows, CRMs, and internal tools via the API.
  • AI-native workflows – Let your assistant research, build, and enrich lists end to end over MCP, with spending always gated on your confirmation.
